MAC Address Vendor Directory

Every network interface ships with a MAC address, and the first half of that address — the OUI (Organizationally Unique Identifier) — is assigned by the IEEE to the company that built the hardware. This directory maps those OUI assignments back to the manufacturers behind them, with a researched profile for each vendor: who they are, what kinds of devices the prefix shows up on, and which specific OUI ranges they hold.

A vendor appears here once its profile has been researched and verified against the IEEE registry — so every entry is a real write-up, not an auto-generated stub. The directory grows as more vendors are researched.

Looking for a specific address? The MAC Address Lookup tool resolves any MAC or OUI prefix instantly, even for manufacturers not yet profiled here.

532 vendors profiled and growing.
